I am trying to make a snapshot from a view with a MKMapview to provide a springboard like folder animation when the user selects an annotation.
The official way to make a snapshot of the current window is presented here. This works fine (though quite slow) unless the mapview is not zoomed in too much and has a "regionThatFits" set. The map & the marker make an unmatched "jump" to the left and the gridlines of the mapview are visible:

I suppose it has something to do with the tiled parts of the map but I don't know how to prevent that behaviour.
Any thoughts?

using target 8.0 MapKit, I would like to define an MKAnnotation (such as a pin, or a custom one) that remains fixed on the center of the map view as the user moves the map around. Once the user stops moving the map, I would like to be able to read the new coordinates of the annotation. How can I do this? This in swift, thank you soo much
You can follow this link to accomplish this task.They are doing something very similar to your requirement. Its quite descriptive. Link
I am working on app which will show the current user location on map.I am using the custom annotation on map view for example a car image.I am rotating this image by finding the angle between two locations.But whenever user rotates the map view my annotation also rotates which is for obvious reason and my image moves in wrong direction.In android we can set flat property to true so whenever user will rotate the map the annotation image will also rotate along with it.
Please suggest something useful.Thank you.
iOS 7 has changed how maps are displayed by apps on the iPhone, and especially how the user configures the map.
The map is displayed like this, with an Info button.
When the user taps the Info button, the configuration screen slides up.
How do I recreate a screen overlay like this in my code? While I don't want the user to be dropping pins, I want the user to be able to switch between different map styles or open the address I'm pointing to in Apple's Maps app.
If you are trying to do a simple overlay view, then look into making an UIView slide up through UIView animations. Other than that, you would need an UISegmentedControl and related code. You would also need to blur the view and make it translucent, so look into my other question and answer on how to properly blur an UIView:How to apply blur to a UIView?
I've never looked into it, but I've heard the only easy way to do a translucent background (as in, without writing your own OpenGL code) is to create a UIToolbar instance.
I'm guessing you'd make a toolbar with no items, just treat it like UIView and add your own subviews (UITableView, etc). It is a subclass of UIView.
Is it possible to animate changes to the coordinates of an annotation on an MKMapView in iOS? Nothing in the API seems to indicate that this is possible, however apps like Uber seem to do this when showing car locations in their map. Perhaps they are calling setCoordinate: multiple times over a short time to give the appearance of animation taking place?
i'm trying to reproduce the kind of map behavior of the app "Stuck On Earth". Here's a screenshot :
Here's the behavior :
On the map, as you can see there is pin
When you click on a pin, it display the picture attach to it. Really important : the picture stai with the pin, and it stays BEHIND it
If you click on the picture, a new controller is called
if you click on the pin, the picture disappear
I'm trying to do something similar. For now, as i can read, i've got two solutions :
Using callout : callout is HELL. I can try to use a false annotation, but MapKit deals with the depth of elements, and the picture is always in front of the pin
Using Custom Annotation : i was going for the plan of making custom annotation view, when the pin is tapped, i launch a method of the CustomAnnotationView, adding (or removing) the thumbnail.
I think the method number 2 could work, but i've got no idea how to deal with the touch on the thumbnail.
Any suggestions or help on this ?
Thanks you !

My colleague devised an workaround by making popup views as subview of the view container which contains the map view. The position can be calculated according to the CGPoint transform in different reference systems.
Original Answer:
I also got this kind of problem, after following the tutorial 'Building Custom Map Annotation Callouts – Part 1', the interaction becomes difficult.
Have you tried the tap gesture recognizer? I added it to a subview, it works, although the code smell bad.
